| description | The invention relates to the field of disinfection and sterilization products, and discloses a chemical indicator and a preparation method thereof.The chemical indicator is applied to pressure steam sterilization parameter indication, and the preparation method of the chemical indicator comprises the steps that indication ink is printed on a transparent material film; the ratio of the coverage area of the indication ink printed on the transparent material film at one time every time to the area of the printing surface of the printing plate is not less than 0.5; cutting the area printed with the indication ink on the transparent material film into a plurality of ink units with set shapes; and the ink unit is attached to the paper carrier to form the chemical indicator. According to the method, the indicating ink is firstly printed on the transparent material film and then transferred to the paper carrier, so that the indicating ink with a larger area can be printed on the transparent material film at a time, t |
